TOOL-HANDLE.

SPECIFICATION forming part of Letters Patent No. 375,786, dated January3, '1888.

v Application filed August 9, 1886. Serial No. 210,418. (No model.) 1

To all whom, it may concern: f Be it known that I, ARTHUR COLLING WELLS,a subject of the Queen of Great Britain and Ireland, and a resident ofManchester, in the county of Lancaster, England, have invented certainnew and useful Improvements in Tool-Handles, of which the following is aspecification.

This invention relates toV that class of toolhand'les in which ametallic outer shell is employed in connection with a wooden plug intowhich a file-tang or a like tang on any tool may loe convenientlydriven, the shell resisting the 'bursting strain and insuring a smoothand symmetrical grasping surface. Heretofore such handles have beenpractically useless after the rst plug became worn out, and, owing totheir greater first cost as compared with the ordinary Wooden handles,could not be economically substituted for the latter.

My present invention consists in a metallic shell of novel construction,in combination with normally-cylindrical or substantially-cylindricalinterchangeable wooden plugs,77 as hereinafter set forth, wherebyprovision is made at once for securely fastening the tang and forreadily and quickly renewing the wooden plug when worn.

It consists, further, in the combination, with such a plug, of a shellof a specific construction having an efficient thrust-swell with anefficient holding-chamber of corresponding curvilinear shape inlongitudinal section within it, so that both may be formed, withoutsurplus metal, by one and the same core enlargement.

A sheet of drawings accompanies this specication as part thereof.

Figure l of these drawings represents an axial section of a tool-handleconstructed according to this invention as it appears before use. Fig. 2represents a crosssection on the line 2 2, Fig. 1; and Fig. 3 representsa smallscale axial section of the same handle applied to a tile', withdotted lines and arrow illustrating the mode of ejeeting a worn plugtherefrom.

Like letters of reference indicate like parts in all the gures.

Orepresents said metallic outer shell, l?, the

wooden plug; F, atriangular tile, representing any hand-tool having adrive-tang, fraud E, an ejecting-pin, which may be any tool or piece ofmetal adapted to be so used. Said outer shell, O, is preferably amalleable-iron easting. The plug P may be of any suitable wood. Theirconstruction is illustrated by Figs. l and 2. The plug is normallycylindrical, with an axial bore, a, to receive and guide the tooltang,and a bevel, b, at its `inner end to facilitate inserting the plug. Theouter shell is externally ot' an approved shape for tile-handies and thelike, including a curvilinear thrnstswell, s, between a terminalferruleA neck,f, and a contracted waist, zo. Within saidncck and waist asmooth cylindrical bore, B B, is formed, and within said thrustswell aholding-chamber, G, of corresponding shape, is formed as a mid-lengthenlargement of said bore. An internal circumferential rib, r, forms astop at the inner limit of the bore B B, and beyond this theshell iscored out with reference simply to the requisite combination of strengthand lightness. In the outer end of the shell a central hole, h, providesfor inserting the ejecting-pin E, as illustrated in Fig. 3.

The wooden plug P having been loosely inserted within the outer shell,O, against the stop-rib r, as shown in Figs. l and 2, the tang t ofthetile or other tool F is inserted in the plug-bore a and driven home,said stop-rib forming anabutment for the plug. The fibers of the wooddisplaced by the tang nd accommodation within the holding-chamber C,where they forni a bulge, w, as seen in Fig. 3. This precludesaccidental escape of t-he plug, while the tang may be driven therefromand a worn plug may be ejected at will in a moment by inserting theejecting-pin E through said hole lz. and driving it lengthwise, asrepresented by the arrow z.

Interchangeable plugs for the handle will be made in quantity and soldby the dozen, so that worn plugs may be replaced by new ones withoutloss of time.

- I am aware that the tool-holder of the dental engine has been providedwith an eiecting-bere in line with its holdingbore to facilitateremoving the tools, and also that a sockethandle7 for dentists tools hasbeen provided with a lateral hole for the same purpose. both of thesedevices provision is made solely for acting on the end of the tang so asto eject the tool. In my device the primary difficulty met and overcomeis to so hold the wooden plug of a handle of wood and metal combined asto provide at once for securely fastening the same and for readilyejecting the plug when it becomes worn. The broad idea of providing anejecting-hole is disclaimed.

I am also aware than the handle-socket of a ferrule has been made ofcurvilinear shape in longitudinal section, but not so as to coact with acylindrical plug, nor so as to be formed within a thrust-swell, as in myhandle.

Having thus described my said invention, I claim as new and desire topatent under this speciiication- 1. In a tool-handle, a metallic outershell constructed with a socket-bore, a holdingchamber curvilinear inlongitudinal section midway of said bore, and an internal circumA Inlferential stop-rib at the inner end of said bore, and having a centralhole in the outer end of the shell to admit an ejectingpin, in combi- 25nation with awooden plug fitted to said socketbore, substantially asherein specified.

2. The within-described metallic shell having a curvilinear thrust swellbetween a terminal ferrule-neck and a contracted waist, 3o andconstructed with a smooth cylindrical socket-bore within said neck andwaist, aholding-chamber curvilinear in longitudinal section within saidthrustswell, and a central hole in the outer end of the shell, incombination 35 with a Wooden plug expanded within said Socket-bore andholding-chamber, for the pur- Vposes set forth.
